s claims. (ci. 12s-19) This invention relates to oven structures, more particularly to those employed in domestic ranges, and it has for its object the provision of an improved oven structure of this character in which the oven lining is removable for replacement orrepair.

At times, it is desirable to remove the oven lining for repair or replacement. Heretofore. in most oven structures to do this it has been necessary to move the range away from the wall to gain access to the fastening means detachably holding the oven lining in its operative position. This invention contemplates an improved oven structure arranged so that the lining can be removed from and replaced in the range without in any way moving the range. More specically, it contemplates such a structure wherein the oven lining may be serviced from the front.

For a more complete understanding of this invention, reference should be had to the accompanying drawing in which Fig. 1 is a side elevation of an electric range having an oven structure embodying this invention, parts being broken away so as to illustrate certain details of construction; Fig. 2 is a fragmentary view of a part of the oven structure shown in Fig. 1, Fig. 2 being drawn to a larger scale than Fig. 1; Fig. 3 is a horizontal sectional view illustrating certain of the elements of Fig. 2 in plan; and Fig. 4 is a view similar to Fig. 2 but illustratinga. modified form of this invention.

Referring more particularly to Figs. 1-3 inclusive, this invention has been shown as applied to an electric range I. This range is provided with walls defining an outer cabinet 2; as shown, this cabinet is provided with a top wall 3, a rear wall t, a front wall 5 and side walls 6 andf'l.. The front wall 5 is provided with an opening-t.

Insertable through this front opening is an oven lining 9 which is provided with a rear wall Iii, a bottom wall II, a top wall I2 'and opposed side walls I3. The oven lining 9 also is provided with a front opening It which when the lining is in its operative position lies in substantially the plane of the opening 8.

Also, when the oven lining 9 is in its operative position its rear wall I is positioned forwardly of the rear wall l of the cabinet so as to leave a space I between them. Mounted within the space I5 are a plurality of spaced-apart supporting brackets I6; in the specic embodiment of the invention illustrated two supporting brackets I6 are employed, one for each lower rear corner of the lining. Each bracket I6 has roughly the shapel of a U, the two legs I1 and IB being secured at their ends to the rear wall l. For this purpose, the leg I1 at its outer end is provided with a pair of upright arms I9 bent upwardly at right angles to the leg, as shown, and these arms are formed with rearwardly oiiset sections 20 which are inserted through openings 2I provided for them in the rear wall 4 in order to secure the leg Ii to the rear wall, as shown. The end 22 of the other leg I8 extends downwardly at an angle to the leg, as shown, and this section is secured to the rear `wall d by means of a screw fastening device 23.

The nexus 26 ofeach U-shaped bracket is pro- '.vided with an outwardly extending ledge 25 upon which the oven lining rests, as shown. The nexus 26 also is provided with an outwardly extending tongue 26 spaced above the seat 25. This tongue, as shown, is lanced outwardly from the material forming the nexus. The seat 25 and the tongue 25 form a slot 2 between them, and received in this slot 2l is -a projection 28 provided at the rear lower edge of the oven lining. As shown, the projection 2S is formed by extending the bottom wall Il outwardly T/beyond the rear wall It, and by folding the lower end of this rear wall about it as shown in Fig. 2.

It will be understood that when the oven lining Q is inserted through the front opening 8 of the cabin'et, the projection 28 is received in the spaces 2 in the two brackets I6 and that when it is so received the rear end of the oven is supported and also it is prevented from moving upwardly and downwardly within the cabinet.

The oven lining 9 is further secured to the brackets i8 by means of a pair of screw fastening devices 29 which are inserted through openings SU provided for them in the rear wall I0 of the lining and whichA are received in threaded engagement in tapped holes 3l provided for them in the nexus 24 of the brackets. Preferably, each screw will be provided with a reduced lead-in section 32 to assist in picking up its tapped Vhole 3|.

The screws 29 are further provided with a slotted head 33, or a hexagonal head, for convenience in screwing them in and out ofV their tapped holes. As shown in Fig. 2, the screw heads 33 abut the rear liner wall around its screw openings, whereby, when the screws are threaded into the brackets I6 tov draw the liner toward the brackets, the heads close the screw openings.

It will be observed that the screw heads 33 are accessible from the interior of the oven. Therefore, to remove the oven lining, it is merely necessary to remove the two screws 29 and pull the oven lining forwardly 'from the brackets. To assemble the oven lining with the brackets, it is merely necessary to insert the lining rearwardly into the cabinet so that the projections 28 are received in the slots 21 and then thread in the two screws 29.

At the front the oven lining is supported by a flange 34 turned inwardly from the front Wall of the cabinet about its front opening 8.

In the form of thev invention shown in Fig. 4, the oven lining 35 is provided with integral rear and bottom walls 36 and 31 joined by a rounded corner 38. Here, the projection 39 for the oven which is seated upon the supporting brackets 40 is formed by Ia separate piece 4I. As shown, this piece has a leg 42 secured to the rear Wall 36 of the lining, a leg 43 secured to the bottom wall 31 of the lining, and a. rearwardly projecting folded section 44 joining the twov legs 42 and 43, as shown. Otherwise the supporting structure for this embodiment of the invention is the same as that shown in Figs. 1-3.

Preferably and as shown, the rear walls of the outercabinet will be provided with stiifening ribs 45 (Figs. 1 to 3), 46 (Fig. 4) adjacent the points of attachment of the bracket legs with the wall, thesen ribs functioning to reinforce and strengthen Vthe wall at the points of attachment.

While I have shown and described particular embodiments of nw invention, it will be obvious to those skilled in the art that various changes and modifications may be made without departing from my invention in its broader aspects and I therefore aim in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of my invention.

What I claim as new and desire to secure by Letters Patent of the United States is:
